Definitions

  • the invention relates to a hold-down spring for disc brakes according to the preamble of patent claim 1.
  • Such a hold-down spring is known from DE 38 11 385 A1. It is intended for a disc brake, in which two brake linings are arranged in a shaft of a brake caliper and fastened by means of a retaining pin.
  • the known hold-down spring consists of a spring wire, which is essentially rectangular in shape and which is supported on the one hand on the retaining pin and on the other hand on the radially outer narrow side of the brake pads. Essentially, only a radially inward force is exerted on the brake pads. Due to a design-related play, however, the brake pads can also move slightly in the circumferential direction and rattle against the walls of the shaft.
  • the object of the invention is to improve a hold-down spring according to the preamble of claim 1, so that rattling of the brake pads is effectively prevented in any case.
  • the solution of the task results from the characterizing part of claim 1. Due to the simple design of the hold-down spring according to the invention with a central section which extends in the circumferential direction above the brake disc and is supported on the retaining pin, the spring arms intended for the radial pressure of the brake pads can be opened be formed in the simplest way and at low cost. Particularly important for the solution of the task, however, is the spring tongue extending from the central section, which is supported on the brake caliper, in order to add additional torque to the brake pads to clamp their guides and brackets rattle-free.
  • an embodiment according to claim 3 is recommended, in which the spring tongue rests resiliently in the radial direction on the brake caliper, preferably on a radial contact surface, which according to claim 4 is formed by a pocket in a wall of the shaft.
  • the bag is easily molded into the casting of the brake caliper without additional manufacturing costs.
  • the hold-down spring is punched out of a piece of spring plate and bent.
  • the brake caliper has recesses which are formed according to claim 6 in a simple and inexpensive manner when casting the brake caliper.
  • the recesses are designed to secure the hold-down spring in its well-defined installation position. If the recesses are arranged axially in pairs opposite one another only on the brake disk inlet side, the hold-down spring can only be installed in its correct position.
  • the brake pads In order to largely avoid clacking of the brake pads in their guides when the brake is actuated, the brake pads must be pressed against their support surfaces in the main direction of rotation of the brake disk when the vehicle is moving forward.
  • the hold-down spring only achieves this in the correct installation position shown and shown. An incorrect installation position is prevented by the fact that there is no recess in the brake disc outlet at least on one axial side of the shaft.
  • the invention is further improved by the measures of claim 8, which represent a further safeguard against incorrect installation of the hold-down spring.
  • a brake caliper 1 of a fixed-caliper disc brake has a shaft 4 in which two brake pads 2, 3 are arranged and fastened by means of a retaining pin 5.
  • a hold-down spring 6 consisting of a single piece of spring plate has a central section 8 which extends in the central region of the shaft 4 in the circumferential direction 10 and wraps around the holding pin 5 in a substantially semicircular manner.
  • Two spring arms 12, 13 extend from the central section 8, which extend in opposite axial directions 11 and are arranged in the circumferential direction 10 at a distance from the holding pin 5.
  • the spring arms 12, 13 are for radially resilient contact the radially outer narrow sides 20 of the brake pads 2, 3 determined.
  • a spring tongue 23 is provided, starting from the central section 8 and intended for support on the brake caliper 1.
  • a pocket 34 is formed which has a radial contact surface 35 for the contact of the spring tongue 23.
  • the spring tongue 23 rests resiliently in the radial direction on the radial contact surface 35 in order to generate a torque about the axis of the holding pin 5.
  • the torque is transmitted via the spring arms 12, 13 to the narrow sides 20 of the brake pads 2, 3 and presses the brake pads against their support surfaces 43, 44 on the brake disc outlet side in order to prevent the brake pads 2, 3 from rattling in their guides relative to the brake caliper 1.
  • the axially side walls 36, 37 of the shaft 4 are provided with recesses 38, 39 into which the free ends 14, 15 of the elongated spring arms 12, 13 protrude without touching the walls of the recesses 38, 39.
  • the brake caliper 1 consists of an inner housing part 16 and an outer housing part 17, which are connected to one another by means of screws 18.
  • the outer housing part 17 is designed symmetrically with respect to a central plane 19 containing the brake disc axis and the brake piston axis.
  • the axially opposite recesses 38, 39 are also formed. Because of the symmetry of the outer housing part 17, a further recess 40 is created, but this has no function.
  • a further safeguard against incorrect installation of the hold-down spring 6 is provided by the arrangement and shape of the pocket 34.
  • the pocket 34 is arranged on the brake disc outlet side and is just wide enough for the spring tongue 23 to be received. Because of the symmetry of the outer housing part 17, there is also a half-pocket 42 on the brake disc inlet side, which, however, is not suitable for receiving the spring tongue 23 because of its small axial width.
